Embodiment Construction

[0029] figure 1 A perspective view illustrating a portion of one configuration of an elongated member 100 generally having a first elongated strip 110 and a second elongated strip 120 cooperatively defining First elongate member edge 130 , second elongate member edge 140 , and elongate member non-coupling region 150 of elongate member 100 . The elongated member 100 generally extends a distance along the longitudinal direction D1 so that the length is substantially greater than the width, but in the drawings, for simplicity purposes, in figure 1 Shown as a shortened segment in . For purposes of this disclosure, the longitudinal direction D1 may be approximately parallel to the 0° axis, and the transverse direction may be approximately parallel to the 90° axis, and the Z axis may be perpendicular to the 0°-90° plane, as figure 1 shown.

[0030] The first elongated strip 110 generally has a first elongated inner surface 111, a first elongated outer surface 112 opposable to the...

Abstract

The invention discloses an apparatus including a housing having a housing aperture, a spring biased retracting reel located within the housing, and an elongated member that includes a first end attached to the spring biased retracting reel and having a second distal end outside of the housing. The elongated member is capable of winding upon the spring biased retracting reel while translating through the housing aperture, where the elongate member further includes an interior chamber defined by an uncoupled region between a first and a second arcuate elongate members and a venting mechanism capable of regulating air flowing in and out of the interior chamber. Each of the first and second arcuate elongate members further include at least a first layer of fiber material and a second layer of fiber material, where a majority of fibers in the first layer of fiber material are oriented substantially perpendicular to a majority of fibers in the second layer of fiber material.

Description

technical field [0001] The technology disclosed herein relates generally to a self-supporting elongate member, and more particularly to a self-supporting elongate member that collapses when the elongate member is retracted into a coiled or coiled configuration. Background technique [0002] Collapsible self-supporting elongated members are generally useful in a variety of technical fields and in various devices such as measuring tapes. When extended, the elongated member is generally self-supporting from one end in a horizontal direction up to a specified maximum protruding length, at which point the elongated member will generally collapse. When flattened, the elongated member may be folded or rolled for storage. Technical limitations associated with such elongated members generally relate to the protruding length of the elongated member, the weight of the elongated member, the size of the collapsed elongated member, the minimum bend radius of the elongated member, and the...
